What Kind Of Agreement Or Pact Resulted From The Washington Naval Conference
Isoroku Yamamoto, who later successfully attacked Pearl Harbor, argued that Japan should remain in the contract. His opinion was more complex, however, because he believed that the United States could overtake Japan by a factor greater than the ratio of 5 to 3, as it had a huge production advantage in the United States, which he had agreed to since he had served at the Japanese Embassy in Washington. After signing the treaty, he said, «Anyone who has seen the Detroit auto plants and the oil fields in Texas knows that Japan does not have the power to have a maritime race with America.» He later added: «The report works very well for Japan – it`s a contract to limit the other parties.»  He believed that methods other than the explosion of construction would be necessary to seize even the opportunities that may have contributed to his commitment to the Pearl Harbor plan of attack. In late 1921, Washington learned that Britain had scheduled a conference to discuss the strategic situation in the Pacific and Far East regions. In order to prevent the conference and meet the demands of domestic policy for a world disarmament conference, the Harding administration called the Washington Naval Conference in November 1921.  The conference agreed on the five-power treaty, as well as a four-power treaty on Japan and a nine-power treaty on China.  The U.S. delegation, led by Secretary of State Charles Evans Hughes, included Elihu Root, Henry Cabot Lodge and Oscar Underwood, the last to lead the Democratic minority in the Senate. The main objective of the conference was to curb Japanese naval expansion in western Pacific waters, particularly with regard to fortifications on islands of great strategic value. Its secondary objectives were to achieve a definitive limit on Japanese expansion and to allay fears of possible antagonism with the British. They should ease Anglo-American tensions by lifting the Anglo-Japanese alliance, agreeing on a favourable naval relationship with Japan and formally agreeing to the Japanese to pursue the open-door policy in China.
The sea contract was concluded on February 6, 1922. The ratification of the treaty was exchanged on August 17, 1923 in Washington and registered on April 16, 1924 in the League of Treaties.  There was less impact on cruiser construction. While the contract provided for 10,000 tons and 8-inch guns as the maximum size of a cruiser, it was also the minimum cruiser that each navy was ready to build. The contract began an 8-inch construction competition, 10,000 tons of «contract cruisers,» which raised further concerns.  Subsequent maritime contracts attempted to remedy this situation by limiting the tons of cruisers, destroyers and submarines. The Four-Powers Pact, signed on 13 December 1921 by the United States, Great Britain, Japan and France, provided that all signatories be consulted in the event of controversy between two of them on «any peaceful matter». An accompanying agreement indicated that they would respect each other`s rights with respect to the various Pacific islands and the mandates they held.
